The word is correct, if you mean some picture was cut away. But should be two p's in "cropped".

Amazing photos! Very Happy I'm feeling very humble with all these incredible photos. Very Happy

These are like works of art.

The two dameselflies are amazing - particularly the one peeping out from behind the stem - the one on the right.

oh that was a mistake because i was too quick...is this right Rik:

ratio = how a motive is ordered in the picture? (golden ratio?)
crop = which part of the picture has cut out?

i think my pictures are not perfect and I think that you can do this just well there...exercise and a lot of patience and naturally a good tripod Wink

I think you are looking for the word "composition".

Let's make an example.

Consider a damselfly hanging head-up on a vertical stem. You must decide how close to put the camera, how to orient it (horizontal, vertical, or tipped), and where to place the damselfly within the picture. These are to "compose" the picture. If you tip the camera so the damselfly crosses the frame diagonally, say from upper left to lower right, we might say "diagonal composition".

After you take the picture, you may decide it would look better with some edges removed. This is "cropping".

You might also decide that the picture would look better if the camera had been tilted when the picture was taken. But it wasn't. In this case, if you have enough spare space around the edges, you can "rotate" the image and then "crop" it to change the "composition".

The word "ratio" has several uses, all centered around the mathematics concept of division. The f-number of a lens is a ratio -- focal length divided by aperture diameter. The "aspect ratio" of an image is width by height -- for example 3:2 for 600x400 pixels, or 900x600 pixels, or 3072x2048. Among macro photographers, "ratio" by itself is sometimes used as slang for "magnification" -- image size divided by object size. But I have not heard it used that way anywhere else.

Wikipedia has a good article on "golden ratio". A rectangle that has the golden ratio is considered attractive, but this describes only its shape -- the ratio of width and height. The term says nothing about how the subject is positioned and oriented within the image. That is a matter of composition.

Does this make sense?

Just saw the two Ischnura elegans damselflies on the front page, and want to congratulate you with this splendid photo.
Quite many damselfly species can be seen "hiding" like in the picture, eyes sticking out on each side of a stem. If you move, they may move accordingly :-)
